i This invention rela-testo certain improvements in sheetretaining posts for loose leaf ledgers, and' has for itsy object to-greatly facilitatethe proper insertion and vremoval of thepost. s

The sheets of loose leaf ledgers are frequently providedwith open Ushaped gates at their margins which gates engage with the usual ledger posts thereby preventing anylengthwise .displacement of the sheets.

But the sheets are also perforated at a suitable locality which perforations aline when thev sheets are properly placed within the ledgeig'and a retaining post is then inserted through one side of the ledger within these perforations the inner'end of the post engaging within'a suitable recess in the opposite face of the ledger, ,the object of this retaining postV being to prevent the sheets from gettingl accidentally displaced when the ledger is noty in use.

Someloose leaf ledgers have a fixed capacity and therefore a solid post is used in this instance, while other ledgers are composed of expansible sections, and accordingly anL expansible telescoping springactuated post is employed. Y'

The drawings illustrate this invention in connection with a spring-actuated telescoping` post, but the invention is equally applij y n showing thepost locked within cablef to a solid post withno change whatever in adaptation.

, Inga ledger having expansible "sections,

ywhen' it is desired to closethe ledger ,theV sections are pressed together and locked as usual, and theresilient ytelescopic post isv inserted through yonev side of the ledger'into "the perforations and engagewith a suitable recess in the opposite side of the ledger and this post is pressed'in4 firmly until its outer. end is substantially iush with'the side of the ledger, and a screwdriver orcoin is inserted within a slot at the end of the post and the latter is given a quarter turn sothat a pin extending laterally from the post will ylock behindthe metal side of the ledger.

These loose leaf sheets clamped within an expansible ledger are quite heavy in the agi sheetsmay sag slightlyin the direction of the length, it frequently happens that, when it is desiredto open up the'ledger', and va coin or screw driver is piaced within thefslot at the end ofthe resilientpost, the latter will not spring out owing to the friction kagainst 1t ci the sheets, and then the ledger must be agitated so as to shake the perforations loose from the post, but it has frequently happened that a post, stuck in this manner,

thereof being sectioned and brokenaway- Figure 2 is an elevationfof the 'post from a different'viewpointv Figure 3 is an elevation of the post similar to Figure lbut showing the handle por tion swung at right angles- Figures: is an end View of the constructionshown at Figure 8 'Figure 5 is a sectional elevationrof loose "leaf expansible members showingv the post inserted therein preparatory to locking, the

'endportions of these members beingr res,

Figure y6 lis a View* similar` to Figure members, and Figure 7 is a broken side elevation showing the hinged and locking handle housed within the check piece of one o'f the ledger members. f

Similar numerals of reference denote like parts in the several figures of the drawing. AA `loose `leaf ledger of the expansible the ledgerk nature liscomposed of the usual yoval-shaped metallic hollow cheelrpieces l and 2, and

telescoping sections Biand t secured respectively to said cheek pieces.

The usual posts withv which the sheets en gage are omitted as they form no part ofthe present invention.

5, 6, are openings cut through the'inner wall of the` cheek piece 2 'and' the sections, and 7 8, are similar perforations cut through the inner wall of the'cheek piece l and the section 3, thesel perforations being opposite each other. n 'f l f .In the outerwall ofl the che-ek piece lis formeda ylongitudinal recess 9 whose inner ies" end leads into an opening 10 that is in aline- Inent with the perforation above referred to, and it is through these perforations .and this openingthat the retaining post isrlnserted. The retaining post which is illustrated is of the usualv type comprising an inner' member `11 and a telescoping outer member 12,*the

latter containing the usual coil spring which functions Vto normally extend these post members.

13 is a handle whose inner end has biturcationsrl which eml race an ear 16 formed on the4 end .ot thepart A1Q, a pin 14 being driven through these bifurcations and ear whereby the lhandle is pivoted to the post and is capable o1c being swung at right angles to the lattenand the pin ,14A is prolonged Vso as to extend laterally 'from tbe inner end of the handle and form a `locking stud 18.

Thehandle 13 has extending therethrough `a vlongitudinal opening 19 within which is a coil s rino' 2O .which bears afrainst a ball 21 .P .D D

`at the lower end of the handle and is tensioned by means 'ota screw 22 which bears againstthis spring, and seats 23 and 24 are formed within the end ot the ear 16 and one edge thereof'so that the ball may engage within these seats and hold the handle respectively in straight and folded positions.

In applying this retaining postA the latter is passed through the opening 10 and the perforations 5, 6, 7, and 8, until its abuts `the outer wallof the cheek piece 2, andthe handle is then grasped and pushed 'inwardly until the stud 18 has passed inside kthe wall of the cheek piece 1, whereupon the finger within this opening and pulls thel i handle outwardly, then gives it aquarter turnv and removes the retaining post.

Vhile the form of recess shown is very convenient 'anyother suitable recess may beY utilized in case it is desired to fold the handle out-ot `the way and the invention is not limited in this respect.

vIn ledgers that have a Fixed capacityl a post of a fixed length is used. and it is merely necessary in such an instance to pivot vthe handle to the end of the post just as in the manner above described, the operation vbeing precisely thesame.

[As la mere mattei' of convenience and `economy inmanufaoture, the pivot pin 14 is prolonged at one end so as to extend laterally from one side of the handle, to form the locking-stud, but it .will be obviousthat this locking stud may project laterally 'from the member 12, since this member always rotates with the handle when the latter is turned to bring the stud' into looking position, and therefore the invention is not Ylimited in this respect. Y

What is claimed is 1. In a loose lealE ledger having side cheek pieces, a sheet retaining post having a'handle pivoted thereto and provided with a laterally extending locking stud, said handle adapted to be turned whereby said stud will lock against its adjacent cheek piece and thereafter fold at right angles weithin a Suitable housing. f Y

2. In a loose leaf ledger, a sheet retaining post having at its outer end a hing-ed handle and provided with a locking stud, whereby after said post has been inserted within the ledger and sheets therein and turned to bring said stud into locking engagement with the ledger, said handle may be swung at right angles to the post. l

3. A construction as inclaim 1 with Vthe addition that a recess is formed atftheside of the ledger within which the handle may be swung so asto lie substantially Hush `with said ledger. j

1. A construction as in claim 1 with the further proviso that the handle is hollow and contains a spring'impelled ball which engages within seats formed. in the post when the handle is opened or closed.

5. A sheet retaining post adapted to be inserted within the'cheek pieces oi'' a loose leaf ledger and having a handle hinged to its outer end and provided with a stud which engages one wall ot the adjacent cheek piece tolock the post when the latter is positioned and the vhandle revolvedVtbe,latter being Capableot being swung at ka right angle to the post proper and housedv lsubstantially flush with the outer aoegot said adjacent cheek piece. s

6. A Construction as in claim (i in which the handle resiliently'seats against the post when alined with the latter or lswung at a right angle thereto.

.7. ln aloose leaf ledger having side cheek pieces, a sheet retaining post structure comprising a rotary sheet retaining post proper and a handle hinged thereto,a locking stud extendinglaterally trom said structure and adapted to engage one wall ot the adjacent cheek piece when the vstructure is revolved and a recessV formed within the side ot said adjacent cheek piece, said handle adapted to be swung at a right angle to the post so as tolie substantially liush with said adjacent cheek piece after said stud has been engaged with said wall.

In testimony whereotn I ax my signature hereto.
